599 Series Rack & Pinion

Valves

Siemens Industry, Inc.

Description

The Flowrite 599 Series Rack & Pinion Valve couples the OpenAir™ Actuator to a 1/2

to 2-inch Flowrite 599 Series two and three-way valve via a linkage. The linkage

transforms the actuator rotary movement into the linear motion required to position the

valve.

Features

• Brushless DC motor technology with stall protection

• Bi-directional fail-safe spring return (actuator dependent)

• Direct or reverse acting selectable by field installation

• All metal housing

Application

The Flowrite valves are used to control water and glycol solutions to 50 percent in small

to large air handling units and central plant applications.

Warning/Caution

Notations

WARNING:

Personal injury/loss of life may occur if you do not perform a

procedure as specified.

CAUTION:

Equipment damage may occur if you do not perform a

procedure as specified.
